ANSI Cylinder Buckling.xls

Uses formulas extracted from American Natinal Standard:
Hydraulic fluid power - Cylinders - Method for determining the buckling load, ANSI/(NFPA)T3.6.37-1991.

The solution requires a numerical solver to avoid using a trial and error method. SOLVER Add-in was packaged with Excel 2003, so this was used in the example to find the correct value for the Critical Load. It is up to the designer to apply an appropriate factor of safety as all cylinders have external applied loads beyond the hydraulic system pressure.
